Background: I'm used to having dead quiet around me, but I currently live in a place with quite a busy street outside my (poorly insulated) window. Listening to cars passing by at random intervals when I'm trying to fall asleep drives me crazy, so my solution right now is to have some music playing (yeah, not on headphones... but still, I thought this was a good forum to ask on).
 
My current (very short) playlist consists of these songs:
 
Albatross - Fleetwood Mac (actually, I think this is going off the playlist soon... too heavy)
Boadicea - Enya (yeah, she sings, but there's no lyrics at least)
Air from the Ouverture No. 3 in D major, BWV 1068 - Johann Sebastian Bach
Chorale from Cantata BWV 147: Jesu Bleibet Meine Freude - Johann Sebastian Bach
Monastery of La Rabida - Vangelis
West Across the Ocea Sea - Vangelis
Canon in D major - Johann Pachelbel
Gnossiennes: No. 1 (Lent) - Erik Satie
 
If anyone have recommendations along the same musical styles, I'd greatly appreciate it (main rule is that there cannot be any lyrics).

You should try doing a search for ambient music on this forum, you should come up with a gold mine.  To get you started look here http://lowlightmixes.blogspot.com/
 
Edit:
I forgot about BW Recknagel Great minimal piano music

 

[Olias of Sunhillow]

Try composer and pianist Ludovico Einaudi. Eden Roc, Una Mattina and Divinere are all regulars on my late night playlist.

Although it's jazz (and I don't think I saw any in your current list), one that always worked for me is Kenny Wheeler's "GNU High" album.  Just drifts you off.

It's just the tiniest bit repetitive (at least at the beginning) but this album is like a Xanax and Valium sandwich.

Absolutely the most relaxing string quartet recording I've ever heard.  

 

[Eee Pee]

Oh man, you need Selected Ambient Works from Aphex Twin.

I got to sleep with either Sigur Ros, Ólafur Arnalds or Angus and Julia Stone. I've always slept with music on through my speakers, just very quietly and my softer stuff.

Generally with Gheorghe Zamfir music, its very relaxing. 
And i fall asleep everytime i listen to it. 

 

[Happy Camper]

Solo piano mostly with some new age mixed.

This one works for me. It can be had used from Amazon for 98 cents.

 

[njones0100]

Just about anything from George Winston. I dare you to stay awake.

I've always enjoyed Eno's "Ambient 1 - Music for Airports" for drifting off to sleep.

 

[AudiA4]

have you tried the album 'in an enchanted garden', it's very good to relax and of course easy-sleeping lol

 

[audiophilefreak]

tried kitaro album

No one has suggested Chopin's Nocturnes yet? Excellent.

Also try some Brian Eno (especially the Ambient recordings), Tangerine Dream, Arvo Pärt, Sibelius, and Galaxy 500.

Galaxy 500 is awesome. Yes, a rock band. They rebelled against the grunge movement by playing softer, slower and quieter. There's nothing quite like them. Underappreciated and very much worth checking out.
